Abstract
A bone grafting material is derived from allogenic or xenogenic bone by a process that includes tanning with glutaraldehyde. The bone may be pulverized, used as a large block, or machined into a precise pre-determined shape, depending on the bone defect to be repaired. Glutaraldehyde tanning of bone yields a stabilized, highly biocompatible, and non-antigenic material which becomes incorporated into host bone when placed adjacent to it.
Claims27
A method of preparing a biocompatible, stable, and non-antigenic bone grafting material from allogenic or xenogenic bone stock comprising
- (a) machining a bone segment to the desired dimensions
- (b) tanning the bone segment by treating it with glutaraldehyde under tanning conditions.
A method of preparing a biocompatible and non-antigenic bone grafting material from allogenic or xenogenic bone stock, comprising:
- (a) pulverizing a bone segment to obtain pulverized bone;
- (b) tanning the pulverized bone with glutaraldehyde under tanning conditions;
- (c) combining the pulverized bone with a gelatinous or semi-solidified carrier.
A biocompatible, non-antigenic and stable bone-grafting material comprising allogenic or xenogenic bone stock machined to a desired shape and tanned with glutaraldehyde under tanning conditions.
A biocompatible, non-antigenic, and stable bone-grafting material comprising allogenic or xenogenic bone stock that has been pulverized or powdered and tanned with glutaraldehyde under tanning conditions.
